This invention relates to machines for cooling stereotype printingplates.

The principal objects of this invention are to provide a means and a method whereby the plate will be cooled by water on its inner or non-printing side, to protect the printing side from the cooling water so as to avoid the necessity of drying the printing surface before the plate goes to the press; and generally, to improve'and simplify the construction and operation of stereotype plate cooling. machines.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompany ing sheet of drawing in which- Figure 1 is aside elevation of a gravity shaving machine constructed in accordance with the present invention, and Fig. 2 is a longitudinal sectional view of the same with certain parts omitted.

Although this invention is not limited to the gravity type of shaving machines. it is particularly adapted thereto. and is shown as applied to that type. .Themachlne 15 illustratedas embodying a frame 10 having an inclined top provided with a horizontal receiving table 11 at one end, and having an inclined run way formed by rollers 12 arranged on an incline for receiving the edges of the plates from the table 11. Located between these'rollers is a fixed saddle 13 over which the plates move along over the longitudinal shaft 14 of the bias. The saddle 13 has a projection or Plates, of which the following is a specifica touching the printing surface.

guard extending up from the lower end substantiallyfitting the interior-of n unfinished plate to protect the operator who places the plate in position from a cam which is located just beyond the guard, but is not shown in the drawings. As the shaft 1% revolves the plate slides down the incline by ance of which operation injures the rollers of the press, the following mechanism is provided.

Surrounding the shaft 14 is a hollow semicvlindrical cooling saddle 63 connected with a source of water supply by-means of a series of pipes 6-4 controlled bya valve 60. The outer con-vex surface of this saddle is provided with perforations 65 and with a series of rifle grooves 66 running substantiallyhorizontally, over which the water discharged from the inside runs in continuous unbroken streams. without producing a spray. Thus the sides of these grooves constitute means for preventing the water from The water discharged from the cooling saddle passes down through the bottom of the machine where it is caught and discharged through a pipe 67. On the driving shaft 68 is a worm 78 operating a worm wheel 7 9 on the shaft '14. This worm islocated in an oil casing '69. The end of the shaft 14 is shown as provided with an internal gear 70 meshing with a gear 71 on a shaft72 journaled to rotate in the frame and provided with brackets 73 thereon carrying a rotary drying brush M for the interior of the plate. The supporting rolls continue to the bottom of the frame, and the plate brings up against a stationary stop 7 and is removed from the machine by hand or, in the absence of the will ordinarily be employed with this machine. 'They are not shownherein as they are now well-known in the art and they can be applied easily tothis machine is several ways.

lVhile l have illustrated and described a preferred embodiment of the invention, and shown it as applied to a particular type of machine, ll am aware that many modifications can be made herein and that it can be applied to many other types of machine without departing from the scope of the invention as expressed in the claims. llherefore it do not wish to be limited to all the features of construction shown, but

What ll do claim is:-

1. lln a machine for finishing stereotype printing plates, the combination of a finishing means, and means supported adjacent thereto for directing water against the backs of the plates to cool them, and for preventing the passage of the water against the printing surfaces of the plates.

2. In a machine for finishing stereotype printing plates, the combination of a finishing means, and means supported adjacent thereto for directing water along the backs of the plates in unbroken streams to cool them, to prevent the passage of the water against the printing surfaces of the plates.

3. In a stereotype plate finishing machine, the combination of a frame, a hollow semicylindrical cooling device, located thereon, along which plates can be fed with their innersides in close proximity to the convex surface thereof, and means for forcing unbroken streams of water through said cooling device against the non-printing sides of the plates.

4. In a stereotype plate machine, the combination of a frame, a hollow cooling device located thereon, means for supporting plates on said cooling device with their inner sides in close proximity to the convex surface thereof, and means for forcing unbroken streams of water through said coolin device against the non-printing sides 0 the plates.

5. In a machine of the character described, the combination of a semi cylindrical cooling device having a. perforated rifled upper surface, means for'directing a cooling fluid through said perforations and along the rifled surface, and means for supporting plates on the cooling device with their nonprinting surfaces in close proximity thereto.

6. la a machine of the character described,

8. In a machine of thecharacter described, the combination of a frame, a semi-cylindrical cooling device having a perforated rifled upper surface, means for conducting a cooling fluid through said perforations and along the rifled surface, means for supporting plates on the cooling device with their non-printing surfaces in close proximity thereto, and means carried by the frame for receiving the water discharged from said cooling device.

9. In a machine of the character described,

the combination of a frame, a cooling device thereon having a perforated upper surface provided with longitudinal curved grooves, adapted to receive a cooling fluid, means for supporting plates on the cooling device with their non-printing surfaces in close proximity thereto, means carried by the frame for receiving the water dlscharged from said cooling device, and means located at the end of the cooling device and in line therewith for drying the inner surfaces of the plates. 1
